Part A:
If a person is chosen at random, the probability that the person is frequently or occassinally involved in charity work is given by
![P(being \ frequently \ involved \ or \ being \ occassionally \ involved)\\ \\= \frac{432}{2881} + \frac{904}{2881} = \frac{1336}{2881}=\bold{0.464}](https://tex.z-dn.net/?f=P%28being%20%5C%20frequently%20%5C%20involved%20%5C%20or%20%5C%20being%20%5C%20occassionally%20%5C%20involved%29%5C%5C%20%5C%5C%3D%20%5Cfrac%7B432%7D%7B2881%7D%20%2B%20%5Cfrac%7B904%7D%7B2881%7D%20%3D%20%5Cfrac%7B1336%7D%7B2881%7D%3D%5Cbold%7B0.464%7D)

![P(being \ male \ or \ being \ frequently \ involved)\\ \\= \frac{1479}{2881} + \frac{432}{2881}-\frac{227}{2881} = \frac{1684}{2881}=\bold{0.585}](https://tex.z-dn.net/?f=P%28being%0A%20%5C%20male%20%5C%20or%20%5C%20being%20%5C%20frequently%20%5C%20involved%29%5C%5C%20%5C%5C%3D%20%0A%5Cfrac%7B1479%7D%7B2881%7D%20%2B%20%5Cfrac%7B432%7D%7B2881%7D-%5Cfrac%7B227%7D%7B2881%7D%20%3D%20%0A%5Cfrac%7B1684%7D%7B2881%7D%3D%5Cbold%7B0.585%7D)
Part D:
If a person is chosen at random, the probability that the person is female or not frequently involved in charity work is given by
![P(being \ female \ or \ not \ being \ frequently \ involved)\\ \\= \frac{1402}{2881} + \frac{904}{2881} + \frac{1545}{2881}-\frac{450}{2881}-\frac{747}{2881} = \frac{2654}{2881}=\bold{0.921}](https://tex.z-dn.net/?f=P%28being%0A%20%5C%20female%20%5C%20or%20%5C%20not%20%5C%20being%20%5C%20frequently%20%5C%20involved%29%5C%5C%20%5C%5C%3D%20%0A%5Cfrac%7B1402%7D%7B2881%7D%20%2B%20%5Cfrac%7B904%7D%7B2881%7D%20%2B%20%5Cfrac%7B1545%7D%7B2881%7D-%5Cfrac%7B450%7D%7B2881%7D-%5Cfrac%7B747%7D%7B2881%7D%20%3D%20%0A%5Cfrac%7B2654%7D%7B2881%7D%3D%5Cbold%7B0.921%7D)
Part E:
The events "being female" and "being frequently involved in charity work" are not mutually exclusive because being a female does not prevent a person from being frequently involved in charity work.
Indeed from the table, there are 205 females who are frequently involved in charity work.
Therefore, the answer to the question is "No, because 205 females are frequently involved charity work".

Answer:
1300 and 700 respectively.
Step-by-step explanation:
Let x be invested in first account and y be invested in second account.
ATQ, x+y=2000 and 101=(4)*x/100+7*y/100. Solving it will give us x=1300 and y=700
